In the dark recesses of a warehouse, a drunken game of cards explodes into a murder. Now the night watchman lays dead. The only witnesses are a housefly or perhaps a cockroach that might be skittering by. That stylized tribute to our seemingly endless appetite for TV programs about forensic science sets the stage for an examination of how, in the real world of police investigations, nature is being enlisted in the war on crime. Sifts through the mayhem, murder, and science that make up the world of forensic investigation with the help of Dr. Jennifer Gardy, of British Columbia's Centre for Disease Control (CDC).

Scientist Bruce Jackson traces ancestry and solves crimes with the powerful tool DNA. Part of the Scientists and Engineers On Sofas Series.
Someone has stolen the legendary cyberbeast Choocroca from cybersite EcoHaven, and the only clue is the culprit’s footprint. The Cybesquad sets out to rescue the massive beast before Hacker can use it to take over Cyberspace. The team uses forensic science to locate the cyberbeast. Part of the "Cyberchase" series.
At the Body Farm, the dead speak. Follows the world's first open-air crime lab with founder Bill Bass, of The University of Tennessee, for a close-up look at how cadavers decay. As proxies for murder victims, these decomposing bodies are studied in the name of science and the cause of justice. Talks about the factors and biological markers that help pinpoint time since death, including wind and weather, insects and carnivores, fire damage, soft tissue leachate, mold, and bacteria. Presents three homicide cases that hinged on data and expertise gained at the Farm, and shows Ph.D. students using forensic science and body processing. Shows human bodies in a variety of decomposition stages.
Ever wondered how art museums decide if a painting is a fake? Nate meets with Dr. Gregory Smith, a forensic art scientist, to follow a painting they suspect is a forgery. They use everything from x-ray fluorescence to electron microscopy to figure this case out. Part of the "Artrageous With Nate" series.
Forensic anthropologists analyze human remains. Their findings aid in the detection of crime by working to assess the age, sex, stature, ancestry and unique features of a skeleton, which may include documenting trauma to the skeleton and its postmortem interval. Please note: Preview of this title is highly encouraged due to the sensitive material that is covered.
Forensic osteological research facilities are outdoor compounds where donated human bodies are studied during decomposition. Using archeological field techniques, researchers discover what happens to human remains when exposed to a number of different environmental conditions. Studying these skeletal remains in different contexts proves extremely beneficial in solving real-life humanitarian and criminal cases. Please note: Preview of this title is highly encourage due the sensitive material covered.
This short video explores the stages of decomposition of animal bodies and shows how microorganisms found during the decomposition process can provide useful information for criminal investigators. Through forensic experiments, scientists have shown that it may be possible to estimate time of death by sequencing the DNA from the microbes found on and around decomposing bodies. Part of the "I Contain Multitudes" series.
In the Pacific Northwest, people are stripping moss for the horticultural trade at such an alarming rate that it's now illegal to harvest it. Ecologist Nalini Nadkarni knows that moss is a key component to the eco-system of the region, which makes it important to study. But this globe-trotting scientist at The Evergreen State College needed a lot of help recording research data from some folks who have much more time than she does. Where better to find potential research assistants with lots of time on their hands than the nearby medium security Cedar Creek Corrections Center? With support from the National Science Foundation, Nadkarni’s idea has been so successful that now the prisoners are starting bee keeping and composting programs, in addition to growing and recording data about moss.
Carl Pennypacker at UC Berkeley runs Universe Quest, a summer program supported by the National Science Foundation to engage girls in science exploration. Some of the summer activities include: looking through a world-class telescope, going out to the beach to measure tides, and designing online games.
A food science professor discusses the chemistry and physics of food preparation and cooking. She also gives an overview of a food science laboratory and its equipment.
With help from the National Science Foundation, Cornell University’s Ornithology Lab is tracking bird breeding biology and the impact of climate change on bird populations. Some of the best information they are getting is from dedicated “citizen scientists” who provide critical data on what kinds of birds are nesting where, the number of eggs laid, and the number of chicks hatched.
Students learn what makes science different from other disciplines. They also explore the many exciting career opportunities in the science filed. Concepts and terminology discussed include: observing, solving problems, health, career, education, and sharing information.
Hawaii's Kilauea volcano is one of the best places on Earth to study processes within basaltic volcanoes. Its high eruption frequency, easy access to lavas, and distinct geologic setting far from plate boundaries or continents allow researchers to address fundamental problems related to active volcanoes. Another constant at Kilauea, besides the flowing lava, has been University of Hawaii geologist Mike Garcia. With support from the National Science Foundation, Garcia has been leading studies of Kilauea for a generation, adding to the extensive knowledge base on this volcano. Two of the primary goals are to determine what has triggered Kilauea’s effusive, explosive cycles over the last 2200 years and when long eruptions, such as the current one, will stop. Part of the National Science Foundation Series “Science Nation.”
Harvard University, electrical engineers Rob Wood and Gu-Yeon Wei, and computer scientist Radhika Nagpal created the “RoboBee,” a miniature flying robot, inspired by the biology of a bee and the insect’s hive behavior. With support from the National Science Foundation and a program called Expeditions in Computing, Wood put together a diverse team of collaborators to get the RoboBee project off the ground. Ultimately, the researchers hope to build a colony in which the RoboBees interact, using their hive as a refueling station. They say RoboBees have the potential to be useful in a number of ways, including search and rescue missions, traffic monitoring, and weather mapping. Part of the National Science Foundation Series "Science Nation."
Since the time of the ancient Greeks, humans have been using spider silk to dress wounds. Scientists now know spider webs not only have healing qualities, they can be stronger than steel. University of Wyoming Molecular Biologist Randy Lewis adds an almost science fiction aspect to the study of spider silk: making large quantities of it by “growing it” in goat’s milk. With funding from the National Science Foundation, Lewis has cloned and sequenced genes for the proteins that make up five different spider silks, some stronger than Kevlar, others more elastic than nylon.
With support from the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA), Georgia Tech biochemist Nicholas Hud and a team at the Center for Chemical Evolution (CCE) are working to chip away at how life on earth began. They are homing in on how chain-like chemicals called polymers first came together and evolved three-and-a-half to four billion years ago. Part of the National Science Foundation Series “Science Nation.”
Stomach ulcers affect nearly four million American's every year. So, what causes them, and how are they treated? With funding from the National Science Foundation, researchers at Boston University are uncovering the mysteries of how H. pylori bacteria is able to survive and thrive in the acidic world of the human stomach.
These days it seems everything is going green including roofs. With funding from the National Science Foundation, Patricia Culligan of Columbia University is studying green roofs, from their effects on storm water runoff and carbon dioxide absorption to claims they impact local climate and save energy.
The scientific method is the foundation of work for scientists. Explains the scientific method in detail serving as the basis for your science fair project. The process of creating a science fair project along with helpful hints for success is described. Other terminology includes: hypothesis, experiment, data, conclusion, data table, and graphing.
